Help, I''m trying to get save/restore working, and I keep running into
troubles.
I don''t know where to look next.
first I had to get to xen-3.0.2 in order to enable CONFIG_HOTPLUG_CPU
guess x86_64 didn''t have it yet
Then I had one success, with one domU, save, restore, etc. [w/debian]
Then I attempted with another domU,
[w/centos and 7G of ram.] and it failed. Since then I haven''t been
able to save any domU.
xm save just fails, and leaves the domU in shutdown state.
[root ~]# xm list
Name ID Mem(MiB) VCPUs State Time(s)
Domain-0 0 251 1 r----- 28.2
old_herbie 3 768 2 -b---- 0.7
[root ~]# xm save old_herbie old_herbie.xensav
Error: /usr/lib64/xen/bin/xc_save 10 16 3 0 0 0 failed
[root@herbieII ~]# xm list
Name ID Mem(MiB) VCPUs State Time(s)
Domain-0 0 251 1 r----- 32.0
old_herbie 3 768 1 ---s-- 0.8
Xend.log says this:

Re: [Xen-users] xm save fails with Error when writing to state file (5):
My appologies, for not figuring this out earlier. The problem was I ran out of diskspace, on the filesystem I was trying to save to. [ the error messages sure helped obfuscate the problem. ] Anyhow, problem solved.
